The essential problem of acute gastrointestinal bleeding is hemorrhagic shock. Using a high-power Nd-Yag laser, transmitted endoscopically by Dr. Nath's triconic quartz fiber, it was possible to occlude massive arterial bleeding ulcers immediately after endoscopic localization. Of 202 bleeding ulcers in the upper gastrointestinal tract, 193 = 96% could be stopped. The mortality rate was reduced in bleeding acute ulcers from 58% to 36% and in bleeding chronic ulcers from 21% to 5.1%.
急性胃肠道出血的根本问题是失血性休克。使用高功率钕钇铝石榴石激光，通过纳特博士的三锥石英纤维进行内镜传输，在内镜定位后能够立即封闭大量动脉出血性溃疡。在上消化道的202处出血性溃疡中，193处（96%）的出血能够被止住。急性出血性溃疡的死亡率从58%降至36%，慢性出血性溃疡的死亡率从21%降至5.1%。
